Rochester Carburetor for Sale

Efficiency and a sophisticated fuel control system device!

Rochester was founded in 1937 by General Motors Company. It provided carburetors for brand new vehicles and spare parts for older cars.

In 1950, Rochester carburetors were installed in Oldsmobile and Chevrolet touring cars. In 1955 (Rochester) developed DuelJet, so other automobile factories adopted it. In 1965 the Rochester Quadrajet carburetor was introduced, luxury vehicles like Cadillac were equipped with it, as well as different Chevy trucks and industrial model vehicles.

The Quadrajet was a well needed unit due to its efficiency and sophisticated fuel control device. The combustion chamber is located in the middle area in every model, in order to avoid fuel spilling complications. The combustion chamber features a relatively small volume capacity, which helps reducing fuel evaporation at the time a hot engine “shuts down”.

The body throttle is made from aluminum material, thus reducing its overall weight.

  • Intake valve allows for simplicity and easy servicing
  • Avoids fuel leakage
